Specification of Letters Patent.

Patented April 24, 1906.

Application filed April 29. 1905. Serial No. 258.064.

To [l/ZZ whom it may concern:

Be it known that I, JAMES Moxnr BROOKS, a citizen of the United States, and a resident of Molena, county of Pike, State of Georgia, have invented certain new and useful Improvements in Dumping-Carts, of which the following is a full and clear specification, reference being had to the accompanying drawings, in which Figure l is a side elevation of my improved wagon, the near wheels being removed for the purposes of illustration; and Fig. a plan view thereof.

The object of this invention is to produce a simple and durable dumping wagon or cart which shall be especially useful where excavated material is to be transferred to a more or less distant point and to be spread over the ground at the place of dumping, thus avoiding the employment of a gang of men to spread the material at the dumping-place, as more fully hereinafter set forth.

To the accomplishment of this object and such others as may hereinafter appear the invention consists of the parts and combina tions of parts hereinafter fully described, and particularly pointed out in the appended claims, reference being had to the accompanying drawings, forming a part of this specification, in which the same reference characters designate like parts throughout the several views.

Referring to the drawings by letters, a designates the rear axle mounted on the wheels I). The box or body a of the cart fits down on this axle and is rigidly secured thereto in any suitable manner, so that the box shall be capable of tilting forward, the spindles of the axle serving as pivots for this tilting action.

The front axle e is mounted on the front wheels 9 and supports a suitable bolster or frame (Z, to which the tongue (1 is secured. Upon this bolster or frame is bolted the lower member g of a fifth-wheel, and on this bearing is rotatably mounted the upper member f of the fifth-wheel, said bearing having rigidly attached to it a cross-bar h. The forward portions of the draft-irons t are bent inward and downward. and pivoted by horizontal pivots 7a to the upturned ends of bar It, there by pivotally connecting the draft-irons with the front axle, so that the front axle may swing not only laterally in the usual manner, but forward and backward. Any other man ner of connecting the draft-irons to the front truck so that the tongue may have practically a universal movement may be employed, as is evident.

The draft-irons t pass rearward outside of the cart-body and are pivotally attached to the same at j, these pivotal points being referably arranged, as shown, in a vertical ine with the axle-spindles.

Journaled in the draft-frame, which, as stated, is composed of the draft-bars i, just forward of the cart-body is a transverse shaft n, on one end of which is a drum m, to which the upper end of a chain 7c is attached and wound, the lower rear end of this chain being connected detachably to the lower forward end of the wagon-body by means of a hook Z, rigidly attached to the body. Pivotally mounted on shaft a is a lever 0, which extends up to a point within convenient reach of the driver and which is provided with a awl p, engaging a ratchet-wheel on the shaft.

The body of the wagon may widen forwardly, so that its forward end shall tend to swing downward. Wren the body is so constructed and it is desired to dump a load, the driver simply disengages pawl p from this ratchet-wheel and permits the forward end of the cart to drop to the ground. Then by the continued forward movement of the ve hicle the load is not only emptied, but spread along the surface of the ground. By the chain-and-ratchet device the driver can regulate the distance the forward cnd of the cartbody shall drop, and in that way regulate the spreading of the material. The chain may be made long enough to permit the cart-body to be entirely inverted, and thus dump the load practically in one spot. This inverting of the body is accomplished by the engagement of its front lower edge with the ground and the continued forward movement of the vehicle. Then by drawing on the chain the driver may pull the cart-body back to its normal position, backing the vehicle if it be necessary to do so in order to avoid the strain that would occur if the cart-body were pulled forward while the vehicle was at a standstill. It is obvious that another drum m and chain k may be employed on the opposite side of the vehicle, if it be found desirable to do so.

It will be observed that the arrangement of parts will not prevent the vehicle from being readily turned around within a minimum of space, and, in fact, the vehicle may be turned in either direction while the load is being emptied and spread.

To close the forward end of the wagon-box, I mount on the draft-frame an end-gate con sisting of a front wall g, preferably inclining downward and rearward, and side walls 9, adapted to slightly overlap the front side edges of the wagon-box. This end-gate is mounted stationarily on the draft-frame so that it will remain in its elevated position when the body is dropped for unloading, as shown in dotted lines in Fig. 1. The lower end of the end-gate is engaged by a forwardprojectinglip 7", carried by the front edge of the bottom of the wagon-body, thereby limiting the upward movement of the front end of the wagon-body. This lip 1" also facilitates spreading the dumped material, as is obvious.

Journaled in rearwardly-extending bearings s s, riveted to the sides of the wagonbox, is a transverse shaft t, whose ends are bent into cranks u, each of which carries a brakeshoe 1),. adapted when the shaft is rotated to be applied to the tire of the adjacent wheel. Rigidly attached to one of the projecting ends of the shaft is an arm w, which extends forward and normally rests on the axle andv is connected by a chain x to the rearwardextending arm of a transverse crank-shaft y, journaled on the draft-frame and provided with a foot-crank 2 within convenient reach of the drivers seat a, also mounted on the draft-frame in a suitable manner. To apply the brakes in going downhill, the driver throws the crank 2 forward, which raises arm w and rocks shaft 25 and throws the shoes against the wheels. This brake device is also helpful in dumping the load, as by first releasing the ratchet device and then the brake the rear end of the wagon-body will be raised by the forward movement of the vehicle, thus dumping the load, and by so proportioning the arm to that when the brake is applied its point of connection to chain a: shall be in horizontal alinement with pivot j, as shown in dotted lines in Fig. 1 ,the brake will remain on during the entire clumping actionthat is, until the driver releases the foot-crank 2. With this dumping device it is not absolutely necessary to mount the wagon-body on the axle so that it will tend to dump automatically, as the friction and leverage will be ample to tilt and dump the body automatically. Another object of widening the box forwardly is to give more capacity to the front end and at the same time facilitate the discharge of the load. The peculiar universal connection between the front truck and the frame is advantageous in that in addition to the usual lateral pp yi swing of the tongue in turning the vehicle the tongue is free to vibrate up and down while the vehicle is passing over rough places without communicating the motion to the body or box.

It will .be apparent to those skilled in the art that various mechanical embodiments of the invention are possible, and I therefore do not wish to be limited to the exact arrangement and construction shown.
